When my son was about one, my sister-in-law made him a Quiet Book. It was such a great gift, that I decided I would come up with my own. So I took the one she made, plus a lot of examples I found online from googling "Quiet Book," and came up with my own set of pages.
This gift was truly a labor of love. I had no pattern, no instructions for putting it together. Just pictures and my son's book (which was put together differently than what I ended up doing). I sketched stuff up on paper and did a "mock up" to figure out how I was going to assemble it all. I know there are people who make and sell these, and my hat is off to you. I just don't know that I could do it and make it profitable....I'd have to charge $35 + a kidney to account for the housework that didn't get done while working on this!
I "super" sewed everything down to make sure no little choking hazards would come off...even used heavy-duty upholstery thread to secure the buttons. I tried to cover several different activities on my pages: textures, counting, zipping, buttoning, velcro, "peek-a-boo," and "I Spy" to name a few. I hope she likes it. I will be making one for my nephew too when he gets old enough to play with it (hmmm....first birthday gift.)
I also picked up a few injuries on this project: I sewed my finger (not the first time I've done this. Once, the needle went through my finger and stopped....and I had to turn the hand wheel to get it out), I cut myself with the rotary cutter, and I stuck a pin into the heel of my hand. Guess I shouldn't sew while
